Kits are available for a little less than that. If you don’t feel confidant enough to do it yourself, go for it. I did my conversion by buying the regulators from Chevy and the motors from Advance Auto Parts. The two switches came from a junk yard (rear door switches, late model S10 Blazer). I have just over 200 bux in the conversion. A friend of mine used a kit from Electric Life, nice fit and seems to be a quality product.
